Description Chen Qi 2013-01-10 03:23:45 UTC

/etc/init.d/hwclock.sh: .: line 23: can't open '/etc/default/rcS'

Here's the root cause:
sysvinit provides /etc/default/rcS.
initscripts and busybox both need /etc/default/rcS.
But there are no dependencies among them. (Of course there should not be.)

So, a seperation of rcS-default from sysvinit is necessary for initscripts and busybox to work correctly.

poky-tiny intentionally does not support system v init. I think the question we need to ask here is why is hwclock.sh getting installed in poky-tiny.

hwclock.sh is provided by busybox.

The above error was encountered when I was exploring poky-tiny.
After I looked into it a little bit, I found it was actually a dependency issue.

As stated above, there are no dependencies among sysvinit, initscripts and busybox. But initscripts and busybox both need /etc/default/rcS which is currently provided by sysvinit.

As I think there shouldn't be any dependencies between these scripts (because the init system can be replaced, and in this case, by tiny-init), I'd like to seperate rcS-default from sysvinit and let initscripts and busybox depend on it.

What do you think about it?

Comment 3 Darren Hart 2013-01-11 16:38:00 UTC

Interesting. Have you determined why hwclock.sh needs /etc/default/rcS? That might need to be established first.

Are the initscripts useful without sysvinit?

Saul, what are your thoughts on the interdependence of these packages?

Comment 4 Chen Qi 2013-01-28 04:52:52 UTC

Now that initscripts will not be built unless the init manager is sysvinit. I think we could just fix the hwclock.sh script by checking the existence of /etc/default/rcS before souring it.

Comment 5 Chen Qi 2013-02-18 07:39:12 UTC

It seems more reasonable to just check the existence of /etc/default/rcS before sourcing it.

Verified with master branch: 0bedc0b80d9b46cbbf4a2c5e120a6aa52cbc7c2e
Run "/etc/init.d/hwclock.sh restart" , there is no such error.
